Why Many Americans End Up Paying for a “Free” Yearly Doctor Visit

After relocating to West Virginia, Steve Kuo enrolled in a new health plan that would cost him $500 a month. One thing made that premium easier to accept: He believed he was entitled to a free preventive appointment, so he scheduled a visit at a nearby clinic.

At the appointment, staff asked about his medical history, and he mentioned earlier kidney issues. Weeks later, a bill arrived showing he had been charged twice for the same visit: once for the preventive checkup, and again for an “office sick visit” tied to the kidney discussion. Kuo said he was baffled and frustrated. “No copayment means no copayment, exactly as stated in the insurance guidelines,” he wrote in an email. “What is written and agreed upon should be honored.”

His experience is hardly unusual. On Reddit, I found well over a dozen similar complaints from the past year alone, with people saying they were surprised by charges for visits they expected to be free.

One woman said she received a bill close to $1,000 for what she thought would be a preventive gynecology appointment. Another said she was hit with roughly $3,000 in charges after an ultrasound she said she had not requested was performed during a preventive visit, and a blood sample was sent to an out-of-network lab. Another person said they were billed $170 for an office visit after briefly mentioning back stiffness.

This is not how the system is supposed to work. Americans may not get much from our health care system, but one benefit is meant to be guaranteed: each year, regardless of insurance plan, patients are supposed to be able to see a doctor for preventive care without cost, including vaccinations, cancer screenings, and heart-health checks. That requirement became part of the Affordable Care Act in 2010.

More than 15 years later, though, patients across the country are still walking into appointments believing they have one free yearly visit, only to leave with bills for sick visits, lab work, and other services. Researchers estimate that Americans pay tens of millions, and possibly hundreds of millions, of dollars each year for care that should be free under the ACA.

Dr. Yalda Jabbarpour, a family physician in the Washington, DC, area and medical director of the Robert Graham Center for Policy Studies, said confusion over what counts as preventive care remains constant in her practice.

“Every single time I’m in the clinic, this issue comes up with a patient. And it’s sad that it comes up,” Jabbarpour said. “In my mind, the blame is not to be put on the patient. The blame is not to be put on the physician. Really, this points to a bigger system issue that we need to solve.”

How did a promise as simple as one free annual doctor visit become something this tangled — and why are patients and clinicians still wrestling with it nearly two decades later?

Patients keep getting surprise bills — and they’re angry

The Affordable Care Act was designed to broaden coverage and make insurance more comprehensive so it would actually help people stay healthy. As part of that effort, lawmakers required insurers to cover certain services, including an annual wellness exam. But Alex Hoagland, a health economist at the University of Toronto, said the law never clearly defined the boundaries of that preventive visit.

“It didn’t establish a clear definition of…all the diagnosis codes and procedure codes and how frequently you get that combination within a year,” he said. “They don’t define what actually is preventive care and what’s not.”

What is usually free, and what can trigger a charge

• Topics that should generally be free to discuss: routine vaccinations, many cancer screenings, diabetes and cardiovascular screenings, contraception.
• Topics that may lead to charges: chronic pain, prior medical issues, other physical or mental health symptoms, including depression.
• If you are seeing that doctor for the first time, you may also be billed a “new patient” fee.

That ambiguity leaves each insurer to draw its own line, and that is where the problem starts. Preventive visits are supposed to focus on screenings and other steps that help protect long-term health, but if you discuss a specific symptom, you may be billed for an office or sick visit, as if you had come in with the flu.

Insurers have a reason to keep the definition narrow, since that reduces the number of claims they must pay in full. Doctors, meanwhile, want payment for the services they actually provide. If a patient raises a more serious issue during a preventive appointment, the physician reasonably wants to be compensated for addressing it.

“I know, particularly in the healthcare space, it’s really popular to blame one party or another, and here I don’t think it’s a matter of corporate greed or physician incompetence or whatever,” Hoagland said. “It’s just a natural mismatch of incentives.”

That is why the phrase “one free doctor’s visit” sounds simpler than it is. Patients may think of it as a single appointment, but in a fee-for-service system, every separate service can be billed separately. The vaccination conversation may be free, but asking about back pain may not be. Blood work can add another charge. As Sabrina Corlette, co-director of the Center on Health Insurance Reforms at Georgetown University, put it: “It’s not like you walk into a doctor’s office and it’s just one thing that happens, right? It’s multiple different things that are happening when you go into a doctor’s office.”

Part of the issue may be the fact that it is only one free visit. Americans like to use benefits they are told are free, and when that is their only no-cost appointment, they may arrive with a long list of concerns, treating it as their one chance to raise everything with the doctor.

That can cause the visit to drift into a sick visit, which not only creates the risk of a surprise bill but can also crowd out the prevention-focused discussion the appointment was meant to cover.

“What ends up happening a lot…is that a patient comes in for their annual visit, and in their mind, that is their time to bring up every single thing that’s been happening during the year, because they see it as the free visit to bring up everything that’s happened during the year. For some patients, that takes up the entire visit,” Jabbarpour said. “They leave, and it’s like, ‘Oh my god, we forgot to do all the screening things: the vaccinations, the cancer screenings, and the cardiovascular risk screening.’ And then something happens down the line because you never address those screenings.”

A 2021 study by Hoagland and Paul Shafer, both then at Boston University, estimated that people with employer-sponsored insurance paid between $75 million and $219 million in bills in 2018 for services that should have been free. Charges were especially common for contraception and cholesterol or diabetes screenings, with some individuals paying hundreds of dollars.

Hoagland said he had personally been billed for preventive visits because he has type 1 diabetes and the system automatically classified the appointment as a diabetes-related visit. Earlier this year, he co-authored another study showing that people with chronic conditions were more likely to be charged for preventive care. Corlette said she, too, was recently billed for what should have been a preventive visit after mentioning an issue in passing. Both are experts in health policy.

“It was literally maybe a 10-second conversation where I would ask the doctor a question about something,” she said. “And that triggered it.”

Colonoscopy offers another example of how blurry the line can be. Corlette said the procedure was one of the first places where the ACA’s distinction between prevention and treatment became obvious. A patient may undergo a colonoscopy as a preventive service, but if a polyp is found and removed, the procedure can stop being treated as preventive, leaving the patient with a bill that could run into the thousands.

“All of a sudden, that would trigger what the patient thought was a preventive service into a cost-sharing obligation,” Corlette said. “Colonoscopies can be thousands of dollars. That was when we were first like, ‘Oh, yeah, this is a more complicated area than I think the lawmakers that drafted this provision originally envisioned.’”

Possible ways to ease the preventive-care headache

The preventive-care promise in the ACA was well meant, and it is also true that more Americans now receive more free preventive services than they did before the law. The main problem may be expectations: people believe they are entitled to a free visit, then feel misled when a bill arrives.

“The difference is before the Affordable Care Act, maybe they anticipated some kind of cost-sharing,” Hoagland said. “But after, they expect it to be free.”

It does not have to stay this way. Corlette’s team at Georgetown University recently proposed giving Americans three primary care visits and two urgent care visits each year with no cost-sharing. She said that approach would make people feel they are getting real value from insurance and could improve long-term health by making primary care easier to use. In her view, the pressure on that single free visit should be reduced.

“In employer-based insurance, a lot of people feel like, ‘What the hell am I getting for my premium each month?’” Corlette said. “We wanted people to feel like they’re getting good value, and we wanted to get to better population health.”

Hoagland also supports at least one no-cost physician visit each year, no matter what is discussed. Jabbarpour said that, over the long run, she would like to see copays removed entirely for primary care.

But broader payment reform will not happen overnight. For now, what can patients do?

One step is for doctors’ offices to be more upfront. Jabbarpour said the MedStar system she works with now calls patients a few days before appointments with a short warning that they could be charged if the conversation turns to additional medical problems. If your office does not bring it up, ask when you book the appointment or when someone calls to confirm it. You can also ask at the start of the visit what the office counts as preventive care. It may also help to learn which services your insurer says are preventive; that information is often on the insurer’s website, and KFF maintains a database as well.

Even then, the solution is not perfect. “What ends up happening is patients come in, and they say, ‘I know I’m not supposed to talk to you about anything else, so I’m not going to tell you about anything else.’ And you don’t want that to happen,” Jabbarpour said. Ask your doctor directly what they consider preventive care, and set those boundaries at the beginning so you know when a conversation may cross into billable territory.

If you want the laws themselves to change, she said, organize and contact your state and federal representatives to ask what they are doing to stop these surprise bills. In the future, Jabbarpour hopes for a health system in which a primary care visit is not so financially high-stakes, and where doctors and patients can address health needs without having to worry so much about billing.

“I think some patients can be managed by seeing us once every year, once every two years, and some patients need to see us monthly,” Jabbarpour told me. “To put all patients in the same box and say you can only see your primary care physician once a year if you want it paid for, it makes zero sense.”
